This patchset covers optimizations in rx (first 7 patches)
and tx (remaining 5 patches) data path.
Running UDP DL/UL traffic on IPQ8074 5G radio showed an average 5-10%
improvement on a 4 core platform

v3:
- Changed rcu_dereference to rcu_access_pointer in
[PATCH 07/12] ath11k: add branch predictors in process_rx
[PATCH 11/12] ath11k: add branch predictors in dp_tx path.
removed redundant check in
[PATCH 02/12] ath11k: allocate dst ring descriptors from
cacheable memory.
v2:
- Addressed internal developer reported segfault and avoid lookup twice
by utilizing idr_remove (patch 12/12 and patch 2/12).
